U.2 and U.3 Host Adapters provide a quick and simple means for test and debug of Solid State Drives (SSDs) based on PCI Express (PCIe) protocols. They support data rates of 2.5 GT/s, 5.0 GT/s, 8.0 GT/s,16.0 GT/s and 32 GT/s. Each host adapter also supports side band signals such as PERST#, WAKE#, CLKREQ# and SMBus (SMBCLK, SMBDAT).
